Specification of Letters Patent.

Eatented Jan. 18, $31G.

Application filed liovember 1, 1906. Serial No. 3%,588.

To all whom it may concern:

lie it. known that l. HANMBAL C. Font), ciliaenot the United States. and resident of Syracuse, in the county of Onondaga and State of New York, have invented certain new and useful Improvements in lype-lVriting I jlachines, or which the following is a specification.

lily invention relates more especially to paper supply and paper i'i'eedinp; devices for typewritijng machines and is designed to improve certain'ieaturesof the automatic roll holder device disclosed in the applica tion of liarry I. Seddon, Serial No. 321,575, tired Juncll-lth, 190G.

Among the objects ot my invention are to provide a rotary materialmarrying device which, after a printing operation, operates auto ritieall to rewind the material unwound during said' printing operation; to provide a govtrnor for controlling the speed of said material-earrying device during its rewinding movements; to provide means for preventing overthrow or excess movements or said material-carrying device at the end its rewinding movements; to provide an improved disconnectible connection between the chute or guide-way for the ma..erial and a so-called rocker platen frame; to provide improved means for supporting the roll "e'and to provide improved s tor go no folded work sheet so the chute l y be included between the l of work sheet. *Cither objects will appear" in the course of he following specification.

the above ends the invention consists of the features of construction, combinations of devices and arrangements of. parts hereinafter fully described and particularly pointed out in the claims.

In the present instance in carrying out my invention, I arrange a detachable frame comprising t shaped side arms on the carriage of the tvpewriting machine, and pivotally mount at the upper end of said frame a casing in which is iournaled a rotary mate riahcar n9; device or roll holder on which a roll of carbon pay or is supported. A chute holder and ch has The carbon paper passes downwardly from the roll holder through the chute and between the platen and the aerial paper feed ral with the casing extends the chute. In connection with this device I preferably-employ folded bill streets of the kind commonly used in commercial billing, each of saith bill sheets being first brought into coiiperation with the chutefone oi the parts of said bill sheet passing in front of said. chute having the carbon paper within it and the other of said parts passing behind said chute, the parts of said bill sheet being guided by improved guiding devices sov as to properly co'c'perate with the chute, the fold of the bill sheet engaging with oneof the sideedges thereof, said side edge thus serving as a side guide. As the folded bill sheet is fed around n ith the platen in the usual way, the carbon paper will be fed around at the same time etwetn the parts of the bill sheet, sothat'whenthe printing instrumentalities are operated one part of the bill sheet will receive impressions directly from the usual inking ribbon and the other part of the bill sheet will receive impressions from the carbon pap r, the result being that two copies of the work are made. \Vhtn the writing on the bill sheet has been finished the latter may be fed forwardly out of the niachineand is then held by fiche operator while the usual paper feed roll rel ase is actuated.

y In connection with the roll holder 1 provide an improved automatic returning mechanism for the carbon paper, which niechanan amount of carbon paper equal to that unwound during the printing operations. The

. actuation of the feed roll release brings the automatic returning mechanism into operation so that the used portion of the carbon paper will be drawn back through the machine to the position from which it was started when the feeding ofthe bill sheet in line space direction was begun. Governing or controlling devices regulate the speed at which the return movement of the roll holder and carbonpaper takes place and I also preferably employ a device in the na .ture of a trictionclutch which while permitting the roll holder to be turned by hand in either direction at the same time prevents or holds it from excess movement when the automatic returningT mechanism isbperat ism is operative to rewind on the roll holder portion may be fed forward and detached.' so that a fresh portion of carbon paper may ing. After the withdrawal of the first bill sheet other bill sheets may be written and the carbon paper automatically returned in the same way until its printing surface has become exhausted, whereupon the exhausted be employed for writing a plurality of succeeding bill sheets.

The invention is shown as applied to the No. 4 Smith Premier typewriter whichv is a machine of the rocker platen-style, the platen being mounted in a platen frame which may be rocked to and fro on the platen carriage. The lower portion of the chute is pivotally connected with the platen frame so that said chute .may be substantially tangential of the platen in either of the positions to which the latter may be rocked, the arrangement facilitating a smooth and easy feeding of the carbon paper to the platen. It will be ObVlOLIS,hO\\-'GVI, that various features of the invention are not limited to the rocker platen style of typewriters but maybe readily adapted to other forms of writing machines.

In the accompanying drawhigs; Figure 1 'isa side view on a reduced scale of the upper tially full-sized fragmentary side view,

' elevation showing the connection partly in section of the carriage and its bearings, part of my invention being shown in combination with said carriage. Fig. 5 is a substantially full-sized fragmentary side elevation, partly in section, showing in novel method of mounting the roll holder.

Fig. 6 is a transverse sectional view of the roll'holder, its casing and the upper part of the chute and the'guide for thework sheet,

said section being taken on a plane represented by the line ae-w in Fig. 3 and looking in the direction of the arrow at-said line. Fig. 7 is a transverse sectional view taken on a plane represented by the line z y in Fig. 3 and looking in the direction of the arrow at said line,-said Fig. 7 illustrating the governing or controlling device for the roll holder. Fig. 8 is a fragmentary front between the chute and the platen frame. v

In the drawings, cornerposts l of the machine frame sustain a top plate 2 on which are fixed a pair of track-ways 3 whichare longitudinally grooved to receive antifriction balls 4Q Cooperating wlth the balls are grooved front and rear bars 5 and 6, respectively, said bars being joined at,

project lateral studs 19, said studs normally engaging with the hooked ends 20 of springcontrolled latches 21 pivoted at 22 in the portions 9 of the side bars of the carriage. A finger piece or lifting handle 23 is socured to the front bar 15 of the platen frame near its left end. The normal relations of the platen, the platen frame and the carriage are illustrated in Fig. 1.

It will be understood that when the lifting handle 23 is raised the platen is rocked forwardly and upwardly, the platen axle sliding and turning on the slide way 10 and the platen being rocked forward to expose the writing.

It is not deemed necessary to describe the construction and mode of operation of the carriage and platenframe at greater length as these parts in themselves are not of my invention and are well known in the art. The carriage, it will be understood, is controlled by a carriage spring and step-bystep letter feeding devices which cooperate in the usual way, when the printing keys of the machine are operated, to move the carriage a letter space distance at a time leftward over the top plate and longitudinally of the track-ways 3. The rocking motion of the platen frame, it will be noted, is transverse of the letter space feed movement of the carriage. .At its right-hand end the platen is provided with a line space ratchet wheel 24 which is actuated by the usual line spacing handle and pawl (not shown) to rotatethe platen on its axis to space between the lines of writing.

Loosely hung on the rear bar 16 of the platen frame are depending arms or links 25 (only one of which is shown) which sup port a feed rollshaft 26. said shaft carrying a two-part feed roller 27 which extends longitudinally of the platen at its rear as will be understood from an inspection of Fig. 4.

The lower ends of the links 25 pivotally support'at 28 a paper plate 29, said plate being maintained 1n cooperative relation with the platen by the rearward extensions of resilient paper fingers 30 supported on the front bar 15 of the platen frame. Upwardly extending arms 31 fixed to the rear lOO sears? bar 16 of the platen frame support leaf springs 32 the lower ends whereof cooperx ate with the feed roll shaft to press the feed roller 27 toward the platen. The forwardly and downwardly bentupper portions 33 of the leaf springs 32 engage studs 34 projecting rearwardly from the arms 31 and said leaf springs are maintained in engagement with said studs by shouldered screws 35 which screw into the arms 51 below-the studs 34. A paper table 36 is secured at the front. side of the arms 31 and extends downwardly and forwardly toward the platen as shown in Fig. 4. A feed roll release lever 37 is fixed to the feed roll shaft 26 at: the left of,the platen, said release lever being provided with a lug 38, which, when the release lever is operated, cotiperates with the rear bar 16 of the platen frame in such way that forward and d wnward pressure on the release lever op' 'erates to swing the feed roller 27 and the paper plate 29 away from the platen to release or free the paper. a

'Referring' now to the devices with which my improvements are more directly concerned I prefer to mount them in a frame on the platen carriage, which frame may be readily detached when it is not desired to make use of said devices. 1' therefore provide an improved construction of detachable frame; but itis to be understood that various features of my improvements are applicable whether mounted on the carriage in the manner presently to be described or in any other suitable manner or whether mounted on the frame of the machine. My improvements are especially useful in billing work and as in such work a tabulator of some sort is commonly employed, It I prefer to mount the detachable frame carry "his my improvements on the tabulator column stop bar. As shown in Fig. 4 a bracket 39 is secured by a screw 40 to the rear bar 6 on the carriage near its righthand'cnd, said bracket being provided with a shoulder 41 which preventsrotary movement of the bracket on its screw. At the left. and rear of the carriage frame as shown in Fig. 1 a second bracket is secured by set screws 43 in a fixed relation with the A toothed column stop bar 44- of the usual construction is remov cai'ri a go frame.

ably secured by thumb screws 45 to the rear end portions of the b ackets' 39 and 42.

Near each end the stop bar 44 is formed with a vertically disposed opening which receives the lower end of the rear arm 46 of a frame rod which is shaped substantially like an. inverted \i' and comprises, in addition to the rear arm 46 which is vertically disposed, an inclined forward arm 47, the two arms 46 and 47 being joined at the top by a curved portion 48. The ends-.of the rear arms 46 are secured to the stop bar 44 in any suitable manner as by cross pins 46% The lower end portion of the forward arm 4? of each frame rod is flattened as indicated at 49 (Figs. land 4) and is formed with a hole which receives a thumb screw 50, the latter entering a threaded opening in the front bar ,5 of the carriage frame. It will be seen that the two Vshaped rods and the column stop bar 44 constitute a. frame which may be readily detached from the carriage by removing the thumb screws 45 and This frame, while comparatively light and adding but little to the weight of the carriage, is strong and rigid and well adapted to. carry the devices presently to b described.

It will. of course, be understood that when it is desired to make use of the talmlator without employing my present invention a column stop bar withoutthe frame rods may be substituted for the one just described or the latter may be detached from the frame rods by removing the pins 46. A hearing block 51 is secured to the rear arm 46 of each frame rod near the top thereof by a pin 52, the two bearing blocks being formed with hearing openings which receive the end portions of a rock shaft 53, the latter being; adapted to turn in the bearing blocks but being held from-endwise motion therein by headed screws 5-4 which screw into the ends of. the rock shaft as shown in Fig. 8. The heads of the screws 54 are adapted to contact with the outer end faces of the bearing; blocks and serve not only to prevent endwise displacement of the rock shaft but also to hold the upper end portions' of the frame rods in proper relation, preventing them from spr ading apart. Crank arms 55 are supported on therock shaft by their hubs 56 which are secured to the rock shaft by pins 57.

The free ends of the crank arms terminate in ring-like bearing portions 58 as best shown in Figs. 3 and 5, the openings in said ring-like portions receiving the outwardly extending hubs 59 and 600i the heads or end pieces 61 and 62 of a casing for a materialcarrying device or roll holder presently to be described. These heads 61 and G2 are preferably of cast metal and are joined by segmental cover or casing proper of sheemetal, said casing being designated by the numeral 53 and being suitably secured tothe end pieces or heads.

It will be understood that the using as a whole comprisesthc heads 61 and 62 and body portion and that said casing is pivotally mounted in the bearing openings in the ring-like ends 58 of the crank arms 55, so that said casing may be turned on its bearings in said crank arms. Furthermore, the rock shaft 53 and the crank arms 55 may be turned in the bearing blocks 51 so-ft'hat the casing abovedescribed may also have a i so rotary motion about the axis of said rock shaft. The left-hand head 61 of the casing in addition to the hub 39 is provided with a boss 6% of lesser diameter, said boss terminating in a head (35. A coiled spring (56 surrounds the boss -t and has one end secured in said boss, the other end of said coiledspring being secured in the left-hand .icrank arm as shown in Fig. The.

spring 66 serves as a counterbalancing spring and tends to maintain the crank arms 55 and .the casing raised in the positions shown in full lines in Fig. 1 and in Fig. The boss (it is countcrbored asv shown at 67 (Fig. 3) and the counterbore receives a plunger 68, the stem (39 whereof extends out: wardly through an opening in the head of the boss and is provided with a finger button 70 for retracting the plunger. Confined between the closed-end of the counterb0.6 67 and the plunger 68 is a coiled spring 71, said spring surrounding the stem of the plunger and tendinglto press said plunger constantly rightward or toward the middle of the machine. The hub of the righthand head 62 is elongated and is formed with a central bore 72 as shown in Fig. 3, the bore 72 receiving a short shaft 73, the diameter of said shaft being somewhat less' than the diameter of the bore 72. Near its left-hand end the shaft 73 is enlarged to provide a bearing portion 74 which cooperates with the left-hand end portion of the bore 72 and outside said bore and contiguous to the head 62 the shaft 73 terminates in a head 75 which is formed with a central depression and across slot. 76. Near its right-hand end the shaft 73 is provided with a pin 77 which cooperates with an'elongated slot 78 formed in'the neck 79 of a knurled finger wheel 80. The neck 79 is counterbored to receive theend portion of the shaft 73 and is provided. at its inner end with a reduced portion 81 which fits in and bears against the bore 72 of the boss 60. Sur

- rounding the shaft 73 within the bore 72 is a coiled spring 82, the inner end of which is held in a slot 83 formed in the bearing portion 74 of the shaft and the outer end of which is adapted to contact with one side of a slot or cut-away84 formed in the reduced adjusted.

- tion.77, 78, turn the is turned it will turn portion 81 of the neck79. The spring 82 tends constantly .to expand, and as its inner end is held fast in the slot 83, said spring, by reason of its frictional engagement with the bore 72, serves to frictionally maintain the shaft 73 in any position to which it may be ,The adjusting operations will be referred to more at length hereinafter. It will be noted that" the shaft 73, when it is turned will, 'by reason. of the pin and slot connecnger wheel 80 and friction spring 82, and when the finger wheel the shaft. During the thrning movements the shaft and finger son of the contact of the head 75 and of the neck 79 with respectively .the inner and outer ends of the boss 60. The plunger 68 and the shaft 73 provide end supports for a main shaft 85 upon which the roll holder, presently to-be described, is mounted. The left-hand end portion 86 of the main shaft 85 is reduced and bears in a central depression in 'the end of the plunger 68. The right-hand end portion of the main shaft 85 is received in the central depression in the head 75 of the shaft 73 and carries a crosspin 87 which engages with the cross slot 76. By this means the shaft 85 is connected with the shaft 73 so that when one is given rotary movement the other iscaused to rotate with it and in effect the bearing portion 74 and the neck 78 serve as bearings for the shaft the pivotal axis of the casing v63 in the crank. .arms 55 are coincident.

Surrounding the shaft 85is a. sleeve 88,

said sleeve being secured at its right-hand end by a screw 89 to a bearing block J0 which bears on the right-hand end portion of the shaft 85. At its leftdiantlend the sleeve 88 is securedby a screw 91 to a hearing block 92 which is adapted to turn on a bushing 93 having a polygonal head 94. The left-hand end portion of the shaft. 85 is threaded and the bushing 93 is threaded interiorly to cotiperate with the threads on the shaft, the polygonal head 9-} affording a convenient means for adjusting said bushing on the shaft. The bushing is screwed on the shaft until its inner end contacts with a stop member 93 which is fixed to the shaft by means of a pin '96.. Said stop member besides limiting the movement of the bush-v ing is provided with a tooth or stopping portion 97 which is adapted to cooperate with a tooth or contact portion 98 on a nut 99 which is adapted to travel back and forth on the threaded portion of the shaft 85 in a manner presently to be described between the stop member 95 and another'stop memher 100 at the right of the stop member 95,

.said stop member 100 being secured in place Endwise movement of the shaft and finger wheel is prevented by rearnearer ea sirable. The teeth arrest the nut abruptly without binding. I

As shown in Figs. 3 and 6 the traveling nut 99 is provided with oppositr'ly'disposed grooves or depressions 104 which coooperate with oppositely disposed corrugations or depressions 105 formed longitudinally in the sleeve 88. To enable the parts-to be sei'nbled the stop-meniber 95 is also formed being fixedin the shaft and the right end of said spring being fixed in the bearing block. The shaft 85 is ordinarily held fixed by the friction of the spring 82 acting through the shaft 73; and the tension of the spring 100, which is 'insufiicie'nt to overcome the friction spring 82, is. exerted to turn the bearing block 00, the sleeve 88 fixed thereto and the nut 99 controlled by said sleeve in the direction of the arrow in Fig. 6. This tends to, cause the traveling nut to travel, as it turns, along the threaded portion of the shaft 85 from left to'right and the spring 100 will be effective to turn the sleeve 88" and the nut 09 until the contact portion 103 on said nut engages with the stop-portion 102 on the step 101 as shown in Fig. 3 which shows the nut in its normal position. The purpose of the constructions will. be more clearly understood from later explanations From an inspectirn of Fig. 3 it will be noted that the distance between the stop member and the head 94 of'the bushing is somewhat greater than the thickness of the bearing block 99 so that the returning movements of said bearing block on'the bushing are not interfered with. l

From what has been said it will be apparent that the sleeve 88. while adapted to turn relatively to theshaft 85. normally maintained in a fixed relation therewith by "vreason of the engagement of the traveling nut 09 with the stop member 100. The sleeve 88. however. which. is ada ted to carry the roll-holder proper, as will presentlv be described, may be turned against the tension of the springlOS and relatively to the shaft 85 in order to unwind'the car bon paper. the the influence of the spring 100 and in order to prevent undue shock, I preferably employ a governing device or retarding mechanism comprising a pair of circular plates or flanges 10? as shown in Fig:

dicatedat 90 and the outer plate 107 parts may beemploved.

terial designated by the numeral 112.

To regulate the speed at which rewinding thereof may take place under The flanges are spaced apartand mounted on the bearing block 90, being held in fixed relation therewith in any suitable manner. Pref erably as shown in Fig. 3, the outer end portion of the bearing block is reduced as inis perforated to fit over the reduced part 00-, the latter being upsetor spread as shown after the outer plate 10? is in place, so as to secure it in fixed relation with thelbearing block 90; Khe inner plate 10? pfe'rfo rated to fit over a reduced part 90* on the block 90,- an-dpef course, must be arranged in place before the sleeve 88 is assembled. I the end of said: sleeve being adapted to corn tact with Said-inner plate 107. and to main tam it againstthe-shoulder. formed by the reduced pai't 90 Arranged between the two plates 10'? as appears in Figs. 3 and 7 are a plurality of members or weights 108, preferably three in number, said weights being hung on shouldered rivets 109, the ends whereof are received in openings in the plates 10?. The weights 108 are provided with friction pads and so during the rapid return movement of the sleeve 88 the weights are adapted to be swung outwardly about the pins 109 by centrifugal force, the degree of which depends on the speed at which the sleeve 88 and the as plates 10? are turned. The ends of the friction pads 110 protrude from the surface of their respective weights and when the latter are swung or thrown. outwardly as just described, the friction pads are caused to en- 100 gage'with the inner face of the right-hand head 62, exerting a friction thereaq'ainst and retarding the turning movement of the sleeve 88. In case the speed becomes too greatit will be automatically reduced by 105 the increased friction of the pads 110.

A tubular material-carrying device orroll holder 111 is arranged on the sleeve 88 and preferably is frietionally maintained in fixed relation therewith, although, if ole 11.0 sired, a positive connection between the two The roll holder carries a roll of carbon paper or other na- The segmental portion 63 of the casinq' er cover for the roll holder and the material carried thereby is at the b ck of the carbon roll 112 bestshown in Fig. 6. Hinged at the top of the casino: at 113 is asegmental cover 11d which normally covers the'front part of the carbon roll and which may be thrown back to expose it for removal or other purposes. As shown in Figs. '0 and '4' the lower edge of the cover 114. terminates a short distance in front of the lower portion of the casino; 63. leaving a space designated by the numeral 115, through which spacethe free'end of the carbon may be drawn. Except for this space or slit the casing and its co er completely inclose the carbon roll holder ordi- 3 6 and 7, the chute being designated therein by the numeral 116. The chute and the cover or casing form in the preferred construction a single frame-like part or frame.

1 The sides 116 of the chute are bent inwardly toward each other to form grooves or slots 116 through which the side edge portions of the carbon paper may pass. The chute extends downwa'rdly and forwardly toward the platen, being normally arranged in a plane substantially tangential of said platen at the rear as shown in full lines in Fig. 1. The lower edge of the chute is inclined and terminates slightly below. an d forwardly of the upper part of the paper table 36, and at its lower left-hand corner the chute is provided, as seen at Fig. 8, with an off-set 117, the lower end of which is curled as indicated at 118 (Fig. 4) to receive a removable pin 119, said pin being supported in ears 120 of a bracket 121. The bracket is secured at the back of the lefthand arm 31 and in frontof the part 33 of the left-hand spring 32, said bracket beingv perforated to r ceive the left-hand stud 34' and being mainhined in place by the lefthand headed screw 35. The right-hand car 120 of the bracket 121 projects forwardly through a slot 122 formed in the paper table 36. By means of the bracket121 and the pin 119 the chute 116 and the platen carriage are pivotally connected together. In order to disconnect, the parts it is only necessary to withdraw the pin 119 which is frictionally secured in the ears 120 of the bracket. V a

My invention is adapted to the. use of writing a' bill sheet having a longitudinal fold therein, and it is'contemplated that when said sheet is to be inserted in the machine it is first placed upon the chute 116,

one part or leaf of the sheet being behind the c iute and the other part or leaf in front thereof. the longitudinal'fold coiiperating with the right-hand edge of the chute. In order to hold both leaves-of the sheet close to the chute I have provided a guide wire 123 bentin the-.rna'nner shown in thedraw-' This guide wire comprises two in s branches, one of whielrpassesback of and the other in front 'of .the chute.' The rear branch lies close; to the back'of the chute beginning-near the lower left hahd corner thereof and inclined upward and toward the at this point.

extends horizontally to theeft beyond the projection 117 where it is bent forward and to the right extending then in front of the v seeps? back of the machine. From the upper end of this off-set portion 123 .the wire isbent end being secured to the rear sideof the casing 63 near the right-hand end of said casing by a screw 124 (Fig. 6). Near the toward the left and toward the front, its

lower left-hand corner of the back of'the chute the wire 123 is bentinto a loop 123 (Fig. 1), and a screw 125 passing through said loop and threaded into the projection 117 ofthe chute secures the wireto the chute From said. ointthe wire chute as shown in Figs. '1 and 8. Said wire is-thence bent upwardly, extending at an inclination toward the right as shown in Fig. 2 at 123, andat 123 about the middle of the chute said wire is bent toward the left, the part 123 thereof extending upward and toward the left to a point near the top of the chute; The upper end of this branch of the wire is thence suitably bent .and is secured to-the'rear of the casing 63 near the left-hand end thereof by a suitable screw similar to the screw 124. Near the point 123 the wire is bent floutward from the ,face of the chute as shown in Fig. 1.

This outwardly bent part of the front branch of the wire and'the off-set part 123 of the rear branch of the wire constitute mouths which receive: the aper conveniently as it is passed over the c ute from the right when placing said paper in positionon the chute.

It will be understood that by means of the single wire shaped and attached as shown, I am enabled to provide a light and efficacious guide for both parts of the work sheet. If desired, an additional guide wire 126, attach'ed to the carriage at its ends by the thumb screws 50,.may be employed for receiving the work sheet and carbon paper as they leave or are fed away fronrthe'platen after being written on, said guide wire 126 being curved "from its ends upwardly and forwardly as shown in Figs. 1 and 2.

Each of the bill sheets comprises two parts. awide part 127 and a narrower part 128. the two parts joining at one side-along their longitudinal edges in alfold or crease 129. The narrow-part 128 is suitably ruled andiorms the bill proper which preferably receives impressions directly -fi-om'the inking ribbon. The wider part 127 preferably loo receives impressions from the carbon paper or other transfer medium. After the bill has been writtenthe two parts are separated along the fold or crease 129 and the part 128 is forwarded to the customer while the part 127 is preferably incorporated in a book which forms part, of the records of. the business, said part 127 being preferably provided with holes 130 for cooperation with pins or other retaining means in the record book.

At the beginning of the work the parts are positioned and'the free end of the carbon paper 112 is passed downwardly from the back of the roll through the opening or space 115 and into the grooves 116 in .the chute. As the free end of the carbon is drawn downwardly through the chute by the operator with one hand, the other hand isused to turn the finger wheel away from the operator, thereby communicating a rotary movenient to the shaft 72, the main shaft and from the latter through the stoppingportion 102 and contact portion 103 tothe nut 99 and thence the sleeve 88. In other words, by turning the finger wheel 80 as described the operator overcomes the friction of the spring 82 and enables the roll of carbon to be turned and the free end to' be drawn downwardly through the chute without disturbing the normal relation between the traveling nut 99 and the stop 100 and without increasing the tension of the spring 106.

The free end of the carbon paper is drawn downwardly until-its leading edge passes out of the chute and over the paper table 36 and is brought into cotiperation with the platen and the paper feed roller, the latter being preferably moved to and maintained in releasing position until the leading edge of the carbon paper has passed between said feed roller and the platen, whereupon the feed-roller is allowed to return to position, clamping the? leading edge portion of the'carbon paper; It will be understood that in this operation the finger wheel 80 has been turned to such an extent that the leading edge of the carbon web is in position to be caught by the feed roll 27 when the stops 103 and 102 are in contact. One of the folded bill sheets may now be arranged in position for being fed into the machine. With its bottom uppermost and with the fold or crease 129 at the right, said bill sheet is brought into cooperation with the chute 116, the wider or record part 127 of the bill sheet being'pa ssed from left to right in front of the chute and betweenit and the part 123 /of the guide wire, the bill proper or narrower part 128 passing behind the chute and between it and the rear part of the guide wire. The movement from left to right is continued until the fold or crease 129 engages with the right-hand edge as shown in Figs. 1 and 3' opera ive .ever,-scrves a useful purposeof the chute, which edge is preferably at right angles to the axis of the platen so that the edge may serve as a side guide for the bill sheetand' position it to be properly fed. The bill sheet is then slid down along the chute until itsleading edge comes into co operation with the feed roll 27. If new the platen beturned in line spacing direction part 128 through the usual inking ribbon so that the type impressions on the part 11% will be made from the inkon the ribbon while the type impressions on the part 127 will be made from the carbon 112. It will further be understood that during the line spacing operations through 'which the bill sheet passes, the lower portion of the. carbon paper will be controlled by the platen and the feed roller and the roll holder will be turned to unroll more or less of the carbon paper from the roll. During the turning movements thus communicated to the roll holder 111 and the sleeve 88, the shaft or axle 85 will beheld fixed by the friction spring 82. Consequently as the sleeve 88 turns it will communicate rotary movement to thetraveling nut- 99' and the latter will be screwed along the threaded portion of the shaft 85 which remains stationary. This movement of the traveling nut axially of the shaft 85 will carry said nut out. of contact with the stopping portion 102 and away from the stop member 100 and will cause said nut to travel along the shaft toward the stop member a distance depending on the amount of carbon paper unrolled during the line spacing operations. After the writing on the bill has been completed the. platen may be turnedin line space direction until the lower edge of-the bill has been moved downwardly and forwardly past the feed roll 27. ()f course, during this movement of the carbon paper the traveling nut 99 will be screwed along the threaded part of the shaft 85 still farther from the stop member 100 and nearer to the stop member 95. The latter is spaced so far from the stop member 100' that it will not be reached by the traveling nut during the writing of a bill sheet even of exceptional length. The stop member 95, howin preventing the unscrewing of the nut from the shaft.

From a consideration of Fig. .3 it will be understood that during the turning moven 90, will be turned to wind up the spring and increase its tension. Initially. the spring 106 is adyusted to have sufiicient tension to efiect a rapid return movement of the partseven near the termination of such return movement. The initial tension may be regulated by removing the screw 89 so as to diseonnect the bearing block 90 from the sleeve 88 and then efiecting the proper adjustment be tween the bearing block and sleeve to give the desired amount of initial tension of the spring 106, after which the screw 89 may be replaced. This initial tension will be in creased owing to the turning movement of the sleeve relatively to the shaft 85 under the influence of thel'ine spacing movements communicated to the carbon paper by an amount depending-on the amount of carbon paper unwound.

The bill having been fedforwardly past the feed roll 27 as above described, the operator may next grasp the upper portion of the bill sheet with the right hand, being careful not to take hold of the free end of the carbon paper, while with the left hand the feed roll release lever 37 is pulled forwardly to move the feed roll away from the platen.

. As soon as the releasing movement of the feedroll takes place the tension of the spring 1.06, communicated throu h the block 90 to the sleeve 88 and roll holder 111 will start automatically to rewind the carbon paper on the roll, turning the latter in the direction of the arrow in Fig. 6. During this rewinding movement the speed at which the roll holder turns will be regulated by the governing device comprising the pivoted arms 108 in the manner hereinbefore described. As the roll holder and the sleeve 88 turn backwardly under the influence of the returning spring 106the traveling nut 99 will be turned back wardly also, the shaft 85 still remaining stationary, and said traveling nut will again move axially of said shaft but in the reverse Y of the former direction or from left to right .the other turning parts.

and toward the stop member 100. The turning movements of the parts and the rewinding of the carbon paper' will continue until the contact portion 103 on the traveling nut engages with the stopping'portion 102 on the stop member 100. By providing the luglike parts 103 and 102, I am enabled to elfect a positive stoppage but without any binding action of the traveling nut 99-on the stop member-100 as might be the case were the flat opposite side faces of these two members permitted to contact with each other to effect a stoppage of the traveling nut and It will be-understoodthat when the part 103 engages with the stop 102 to arrest the traveling. nut, and through it the roll holder, a considerable force is suddenly applied to the shaft 85 tending to turn said shaft in the direction any suitable means.

wer

function of the spring will be understood from a consideration of Fig. 3. Theforce applied tothe shaft 85 by the traveling nut is communicated .to theshort shaft 73 and tends to turn the latter also; but through the slot 83 this force is also communicated to the left end of tl'iespring 82 with the result that the tendency of said spring to unwind is increased, and said spring is caused to bind more closely than before in the bore 72 and any motion-of the parts isprevented. Since the return movement of the traveling nut along the shaft 85 from left to right is of the same extent as the first part of its movement from right to left along said shaft, the

amount of carbon paper rewound will be the same as the amount. unwound during the line space movements; and when the rewinding movement ceases the lower free end of the carbon will be in the position from which it started when the feeding of the bill sheet around with the platen was commenced; A second bill sheet may now be introduced, written upon and fed through the machine as before, the same portion of the carbon Daper again being used to reproduce the type impressions on the record portion of the new bill sheet. Thereafter the carbon paper may be automatically restored to the first position by again operating the feed roll release lever in the manner above described.

The operations outlined above may berepeated with a plurality of succeeding bill sheets until the lower portion of the carbon paper becomes exhausted from use. When this occurs the carbonpaper may be drawn forwardly around the platen until the used portion or section has entirely passed out of the machine. whereupon it may be severed If, now, the feed r'oll release lever be operated, the spring 106 will act to rewind the carbon paper until its lower free end Will have been drawn backwardly around the platen and up through the chute a distance from the feed roller equal to the length of the used portion of the carbon paper, which has been severed or cut away. .Before introducing the next succeeding bill sheet, thefinger wheel 80 may be turned rearwardly as before by the operator and the carbon paper drawn downward through the chuteagain until its free end is soon as the writing on the bill sheet has been iii heave? finished with the result that said bill sheet will be drawn backward, with the carbon paper to the starting point and may be removed from the machine behind the platen instead of being fed forward and removed from the front. This second method is 'per haps to be preferred when the upper portion only of the bill sheet is written upon.

lVhen the roll of carbon paper has become exhausted, the plunger 68 may be retracted and the shaft 85 carrying the roll holder may be removed from the machine. Then the roll holder 111 maybe slipped off the sleeve 88 and replaced by another roll holder carrying a fresh roll of carbon paper, after which the roll holder may be replaced, the cross-pin 87 on the shaft 85 being caused to reengage with the cross slot 76 and the reduced end 86 of the shaft reengaging with the bearing opening in the plunger (38.

The clutching device comprising the friction spring 82 does not interfere with the manual turning of-the finger wheel 80 backwardly as has been seen. The construction is also such that the forward turning movement of said finger wheel and of the carbon roll holder, is not prevented. The slot 84 in 'which the right-hand end of the spring 32 engages is of considerably greater width than the diameter of said spring and normally, as will be apparent from a consideration of Fig. 3, the end of the spring will, because of the tendency of the latter to unwind, engage with the side of the slot 84 which is uppermost in Fig. 3 and will maintain the end of the'slot 78 which is lowermost in said Fig. 3 in contact with the pin 77. When it is desired to turn the finger wheel 80 and the carbon roll forwardly, said finger wheel will be turned a distance equal to the length of the slot 78 before any turning movement is communicated to the shafts 73 and 85. Durin this independent turning movement of the linger wheel 80 the side of the slot 84 will coiiperate with the engaged right end of the spring 82 to wind up the latter sufiiciently to prevent any clutching or binding movement suiiicient to hold the shafts 73 and 85 from turning.

When it becomes necessary, in the course of thework, to inspect the line being written, the lifting member 23 is raised to rock the platen forwardly in the usual manner from the position shown in full lines in Fig. 1 to. the position indicated diagrammatically by the dotted lines in the same figure. During this forward rocking movement of the platen, the platen frame will be swung about its pivots 19 and the casing, roll holder and chute will be swung downwardly and forwardly to the positions indicated by the dotted lines in Fig. 1. During the downward and forward movements of ,the roll holder. casin thecrank arms 55 will swing downwardly, turning .the rock shaft .53 in its bearings while, at the same time, the casing will have a further turning movement on its own axis in the ringlike parts 58 on the crank arms. During this movement the tension of thespring 66 at the left of the casing is increased. The combined swinging movement thus com municated to the easingis brought about from its connection with the platen frame through the chute 116. The lower end of the chute is swung forwardly with the platen frame, the pivotal connection between the two permitting an easy change in the relations of the parts. In the new position of the chute it will be seen that it is substantially tangential of the platen at the rear thereof as it wasalso in normal position. This arrangement prevents rumpling or buckling of the carbon paper during back and forth rocking movements of the platen.
